A MMoNlA-,GAS GENERATOR.

SPECIFICATION forming 'part of Letters Patent No. 376,905, dated January 24,1883.

Applicati: n filed September 2 3, 1887. .Serial No. 250,882. (No model.) f y To (LZZ whom ,it may concern'.-

Be it known that I, MATHIAS PoscrrINeER, a citizen of the United States,residing at Louis' ville, in the county of J eiferson and .State of Kentucky, have invented certain new and useful Improvements in AmmoniaGas 'Generators; and I do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled by the horizontal partitions a a ai. The tubes w and y are attached to the partitions a and a3, respectively. rlghe tube w extends into the gas receiver B, which forms an upper portion of the chamber A. The tube y passes through the tubes :c and w into B. The tubewhas one part of the circumference of' theupper end lower than the other part, so as to allow the ammonia to flow from the tube C2 into the tube C3 over the lower part Vof the circumference, and at the same time to'permit thegas generated in the tube C3 to pass upward through it unobstructed bythe ammonia. The large horizontal tubes C C2 C3 C4 are attached to the side of the chamber A,- and each opens intoa com-'f partment formed by the partitions a a2 a3. These tubes lie in a vertical plane to economize space. Their free ends pass through circular openings in the stand D, and are thereby supported. v

E are heads covering the freeends of the tubes C C2` Ca C, and which have the manifolds F attached to them.

G are coils ofsteam-pipe which connect the manifolds F and FV.

H* is the steam-inlet pipe, which connects with a boiler.' The steamY passes through H into the upper part of the manifold F,through the upper pipes of the coil G into the manifoldk F', and then through the lower pipes of G into the lower part of the manifold F.

I are pipes through which the steam passes from the rlower part of the manifold Finto the and sof on through the next succeeding manifolds and coils of pipe to J--the steam'fo`utlet wateresor LOUISVILLE, KENTUCKY, YAssrelvtm rosuLzEE l upper part ofthe next succeeding manifold F,

M is the outlet-pipe for the ammonia', which j l isweakened in its passage through the gener- Y ator by 'coming in contact with the heated coils of steam-pipe and having the gas driven from it by evaporation.

O is a pipe through from the receiver B.

which the gas lpasses Inpractice the ammonia is vintroduced intov the generator throughthe pipe K, lsupplying first the upper compartment of the chamber'A and the tube C', and then successively supplying the other compartments of Aand the tubes ,C2 O3 C* by flowing through the upper tube L, y i f the tube x, and the lower tube L, and then in a state of weak ammonia it passes out through the outlet-pipe The coils of pipe G, which lie below the level of the'ammonia in the large tubes, are heated by means of steam conveyed lfrom a boiler through the pipe H, and by the heat thus supplied the gas is drivenoffro'm Y the ammonia and passesfrom the tube'G and the upper compartmentof A, and through'the f tubes w, x, and y from -the other compartments of A and the tubes C2 C3 Cfinto thegas-receiver B, from which it passes through theroutletpipe O.

-Ihe chamberA and the tubes C O2 CSCt as l far as thevstand D may beincascd in .wood orl other material to prevent the radiation of heat.

' f Any number of vrows of tubes C C2 C3 Cand anynumber of tubes in a row maybe used to. u

attain the desired capacity of the generator,

which has as many compartments in'the cham- Y ber A as there are tubes in a row.

Among the advantages of my invention are:

the large heating-surface; the ready passage of gas from the liquid into the gas-receiver; the gas is dry, not having to pass through much of the liquid; a large percentage of the gas is Ico driven out of the ammonia inpassing through 1 i the generator; the small quantity ot` ammoniaA ments by partitions a. ail a, large tubes C C2 C3.

G, coils of steam-pipe G, upper and lower pipes L, and tubes w, x, and y, substantially as and for the purpose set forth.

2. In an ammonia-gas generator, the combination of a chamber, A, dividedinto compartments by partitions a a2 a3, large tubes C C2 C3 C4, coils of steam-pipe G, and connecting-pipes I, to give a large heatingsurface, substantially as and for the purpose set forth.

3. In an ammonia-gas generator, the combi` nation of a chamber, A, divided into compartments by partitions a a2 as, large tubes C C2 C3 C4, upper and lower tubes L, and tube w, to

allow the ammonia to pass through the generator, substantially as and for the purpose set forth.

4. In an ammonia-gas generator, thecombination of a chamber, A, divided into compartments by partitions a a2 a3, large tubes C Cz C3 Ci, and tubes fw, x, and y, to allow the gas to pass to the receiver dry, substantially as and for the purpose set forth.

5,. In an ammonia'gas generator, the combination of tubes C C2 C C4 with pipes L, which permit the ammonia to flow from one tube to another, substantially as and for the purpose set forth.

6. In an ammoniagas generator, the combination of tubes C C2 C3 C4 with a pipe, fc, allowing the ammonia to How down and gas to rise simultaneously, as and for the purpose set forth.

In testimony whereof I aix my signature in presence of two witnesses.

MATHIAS POSCHINGER.
